Positive definiteness and stability of parametric interval matrices [PDF]
arXiv, 2017 We investigate positive definiteness, Hurwitz stability and Schur stability of parametric interval matrices. We give a verifiable sufficient condition for positive definiteness of parametric interval matrices with non-linear dependencies. We also give several sufficient and necessary conditions for stability of symmetric parametric interval matrices ...

On the Hyers–Ulam stability of the linear differential equation
Journal of Mathematical Analysis and Applications, 2011 AbstractWe obtain some results on generalized Hyers–Ulam stability of the linear differential equation in a Banach space. As a consequence we improve some known estimates of the difference between the perturbed and the exact solutions.

Ulam-Hyers Stability and Ulam-Hyers-Rassias Stability for Fuzzy Integrodifferential Equation
Complexity, 2019 In this paper, we establish the Ulam-Hyers stability and Ulam-Hyers-Rassias stability for fuzzy integrodifferential equations by using the fixed point method and the successive approximation method.

Tableau Stabilization and Rectangular Tableaux Fixed by Promotion Powers [PDF]
arXiv, 2019 We introduce tableau stabilization, a new phenomenon and statistic on Young tableaux based on jeu de taquin. We investigate bounds for tableau stabilization, the shape of stabilized tableaux, and tableau stabilization as a permutation statistic. We apply tableau stabilization to construct the sufficiently large rectangular tableaux fixed by powers of ...

Hyers--Ulam Stability of Mean Value Points
Annals of Functional Analysis, 2010 We prove the Hyers--Ulam stability of the Lagrange's mean value points and the Hyers--Ulam--Rassias stability of a differential equation derived from the equation defining the Flett's mean value point.

Convex conditions for robust stability analysis and stabilization of linear aperiodic impulsive and sampled-data systems under dwell-time constraints [PDF]
arXiv, 2013 Stability analysis and control of linear impulsive systems is addressed in a hybrid framework, through the use of continuous-time time-varying discontinuous Lyapunov functions. Necessary and sufficient conditions for stability of impulsive systems with periodic impulses are first provided in order to set up the main ideas.

Stability analysis for a class of nonlinear time-changed systems [PDF]
arXiv, 2016 This paper investigates the stability of a class of differential systems time-changed by $E_{t}$ which is the inverse of a $\beta$-stable subordinator. In order to explore stability, a time-changed Gronwall's inequality and a generalized It\^o formula related to both the natural time $t$ and the time-change $E_{t}$ are developed.

Legendre's Differential Equation and Its Hyers-Ulam Stability [PDF]
Abstract and Applied Analysis, 2007 We solve the nonhomogeneous Legendre's differential equation and apply this result to obtaining a partial solution to the Hyers-Ulam stability problem for the Legendre's equation.
